AUGUSTE MONNIER, OF SACRAMENTO, CALIFORNIA.

IMPROVEMENT lN WATCH-CLEANING FLUIDS.

Specification forming part-of Letters Patent No. 171,035, dated December14, 1875; application filed August 27, 1875.

To all whom it may concern:

Be it known that I, AUGUSTE MONNIER, of Sacramento city and county,State of California, have invented a Watch-Cleaning Fluid; and I dohereby declare the following description is sufficient to enable anyperson skilled in the art or science to which it most nearly appertainsto make and use my said invention without further invention orexperiment.

The object of my invention is to provide a compound for the cleansing ofwatches and other jewelry, or mechanism (which contains no silver)without the aid of a brush, or any friction with alcohol and chalk, orother substance, thereby preventing the wear which is usual in suchcases, and cleansing much more perfectly, and with less time.

To form my cleansing-fluid I take the following ingredients: Distilledwater, eleven ounces pure white castile-soap, three pennyweights;cyanide of potassium, fifteen grains.

As this compound will keep but a short time, I make it from time to timeas needed,

and use it as soon as practicable.

Everything being in readiness, a sufficlent quantity, say half a pint,is placed in a small porcelain-lined iron vessel, and is heated to theliquid for one minute, the works are quickly removed, and plunged into abath of distilled or rain water, where they are thorough- 1y rinsed.After this operation they are placed in an alcohol bath, and finally arethoroughly dried in boxwood sawdust.

A camels-hair brush may be used to remove any adhering particles ofsawdust, when the parts will all be found much cleaner than when cleanedin any other manner, and a watch thus cleaned may safely be warrantedfor two years.

This fluid can be used for brightening and removing corrosion fromsteel, brass, or gold jewelry and other articles. It is of especialvalue in cleansing watches with nickel movements, and by its use thedamaging wear of the ordinary methods of cleaning is avoided.

By its use a watch can be more thoroughly cleaned of rust, grease, andforeign substances in twenty minutes than can be done in two hours byordinary processes.

Having thus described my invention, what I claim, and desire to'secureby Letters Patent, is

The compound herein described for cleansing watches, jewelry, andtyotherarticles, consisting of distilled water, pure castile-soap, and cyanideof potassium, the proportions be ing substantially as herein described.

AUGUSTE MONNIER.
